How AI transforms stock market research — from hours of manual fundamental and technical analysis to instant multi-dimensional stock analysis. Learn how Diplyzer covers the entire equity research workflow.
The information advantage in stock market investing used to belong exclusively to large institutions — analyst teams, Bloomberg terminals, proprietary data feeds, and quantitative models. Individual investors worked with public filings, delayed data, and generic screeners.
AI democratizes the research stack. Diplyzer gives every investor access to the kind of multi-dimensional, real-time, synthesis-capable research that previously required an entire analyst team.
A thorough stock analysis covers at least six distinct dimensions:
Professional analysts spend 20-40 hours on a single initiation report. Individual investors rarely do more than one or two of these steps before buying.
AI doesn't replace judgment — but it makes all six steps accessible in minutes.
The stock market has approximately 4,964 publicly listed companies in the US alone. AI narrows the universe to a high-quality shortlist:
Value + Quality screen:
"Find S&P 500 stocks with a P/E ratio below the sector median, Piotroski F-Score above 7, positive free cash flow growth over 3 years, and an Altman Z-Score in the safe zone. Rank by Piotroski F-Score."
Momentum + Fundamental screen:
"Scan the Nasdaq 100 for stocks that are: in a confirmed technical uptrend on the daily chart, have beaten EPS estimates in at least 3 of the last 4 quarters, and have seen analyst estimates revised higher in the last 60 days. Show the top 10."
Smart money following screen:
"Find stocks where insiders (CEO or CFO) made an open market purchase over $500,000 in the last 45 days AND where at least one major institutional investor opened a new position last quarter. These are the stocks where insiders and institutions are aligning."
Once you have an idea, AI delivers the complete analysis in one conversation:
"Complete stock analysis for [company]: (1) technical chart — trend direction, RSI, MACD, key support/resistance levels; (2) fundamental health — revenue growth trend, gross and operating margin trend, free cash flow, Piotroski F-Score; (3) valuation — current P/E vs. 5-year average and sector median, price-to-free-cash-flow; (4) insider and institutional activity — recent Form 4 purchases or sales, any 13F changes last quarter; (5) analyst consensus — current rating, price target vs. current price, any recent upgrades or downgrades; (6) upcoming catalysts — next earnings date, any significant events in the next 30 days."
This is a complete equity research briefing. A junior analyst would need half a day to compile this manually. With Diplyzer, it's a single request.
Earnings season is when the most significant, most predictable stock moves occur. AI transforms earnings research from scrambling to systematic:
Pre-earnings preparation:
"Pre-earnings research for [company] reporting [date]: last 8 quarters of EPS and revenue beats/misses with post-earnings stock reactions, current consensus estimates, the implied earnings move from options, key things management said on the last call, and current insider activity."
Scanning for opportunities:
"Which S&P 500 companies are reporting earnings this week? For each, show me: the current EPS estimate, the stock's year-to-date performance, and whether the stock has historically beaten estimates in the last 4 quarters."
Post-earnings analysis:
"[Company] just reported earnings: EPS of [X] vs. [estimate] consensus, revenue of [X] vs. [estimate]. The stock is [up/down] [%] in after-hours. Was this result fundamentally good or bad? What guidance did management provide? What are the key takeaways for the stock outlook?"
The core of value investing — finding businesses trading below their intrinsic worth — is an information-intensive process. AI makes it systematic:
DCF and intrinsic value:
"What is the estimated intrinsic value of [company] based on a discounted cash flow analysis? Assume [X]% revenue growth for 5 years tapering to [Y]%, a [Z]% discount rate, and a [X]× terminal multiple. How does current price compare to this DCF value?"
Graham Number:
"What is the Graham Number for [company]? (Formula: √(22.5 × EPS × Book Value Per Share)). Is the current stock price below this value?"
Deep value with financial health confirmation:
"Find the 10 cheapest stocks in the S&P 500 by price-to-book ratio that also have an Altman Z-Score above 2.5 (not financially distressed). These are potential value opportunities that are cheap without being in financial trouble."
Beyond individual stocks, AI helps manage research at the portfolio level:
Portfolio health check:
"I own positions in [list of stocks]. For each: (1) what is the current Piotroski F-Score, (2) has the technical trend changed in the last month, and (3) are there any upcoming catalysts I should be aware of? Which positions look weakest right now?"
Sector allocation review:
"My portfolio has the following allocations: [list]. How concentrated am I in individual sectors? What are the correlations between my positions? Am I well-diversified or effectively making a concentrated sector bet?"
Portfolio screening for exits:
"Which of my holdings [list] have the weakest fundamental momentum — declining margins, deteriorating F-Score, or negative earnings estimate revisions? These are candidates to review for potential exit."
The gap between AI-assisted stock research and traditional retail research is not just speed — it is depth and consistency:
| Research Dimension | Typical Retail Investor | With Diplyzer |
|---|---|---|
| Technical analysis | 1-2 indicators, one timeframe | 70+ indicators, multi-timeframe synthesis |
| Fundamental check | P/E ratio, maybe revenue | Full financial statement trends, FCF, F-Score, Z-Score |
| Valuation | Compare to sector P/E | DCF, Graham Number, historical averages, peer comparison |
| Catalyst check | Rarely | Always — earnings, insider activity, institutional 13F |
| Analyst consensus | Sometimes | Standard — with estimate revision trend |
| News/sentiment | Headline reading | Structured search and synthesis |
The consistent application of rigorous research criteria — rather than shortcuts — is what builds reliable portfolio performance over time.
